Does it always return TRUE, or FALSE ? If it always return TRUE, you can print it to see what it is. I experienced almost the same problem one week before, and finaly found that there's a session variable of the same name as the one checked in if(). As for variable checking, sometimes I just use the C style: if( $var ), and this also work perfect. Alex
